General

YCH7-125 series isolating switch is suitable in the resistive circuit of AC 50/60HZ,ratedvoltage 230/400V,rated current up to 125A.
It’s used primarily forcircuit’s turning on or off in non-load edsituation.And it functions onconnection and isolation between lines and power,especially suitable to isolate powereffectively and prevent circuit breaker from dosing accidentally when maintainthe circuit inorder to ensure the safeoperation of maintainer
Standard:IEC600947-3
